When a triple fault happens [0], we now get at least a log message. This helps to better understand the root cause of sudden reboots. Broader context: We experience reboots caused by triple faults in edk2 (6 months old as well as recent). They happen so early in the boot that one doesn't really see them without looking at the VMM log. An automatic system reset plus reboot often hides these situations - now they are at least more visible in the log. PS: Printing the registers to get more debugging help doesn't help, as the guest already triple-faulted - the CPU state of the root cause doesn't exist anymore.
